TLDR
The PROCHECK suite of programs as mentioned in this paper provides a detailed check on the stereochemistry of a protein structure and provides an assessment of the overall quality of the structure as compared with well refined structures of the same resolution.Abstract:
The PROCHECK suite of programs provides a detailed check on the stereochemistry of a protein structure Its outputs comprise a number of plots in PostScript format and a comprehensive residue-by-residue listing These give an assessment of the overall quality of the structure as compared with well refined structures of the same resolution and also highlight regions that may need further investigation The PROCHECK programs are useful for assessing the quality not only of protein structures in the process of being solved but also of existing structures and of those being modelled on known structuresread more

TL;DR: This article determined the structure of rhodopsin from diffraction data extending to 2.8 angstroms resolution and found that the highly organized structure in the extracellular region, including a conserved disulfide bridge, forms a basis for the arrangement of the sevenhelix transmembrane motif.

AQUA and PROCHECK-NMR: programs for checking the quality of protein structures solved by NMR
TL;DR: The AQUA and PROCHECK-NMR programs provide a means of validating the geometry and restraint violations of an ensemble of protein structures solved by solution NMR, and their outputs include a detailed breakdown of the restraint violations.

TL;DR: Geometrical validation around the Cα is described, with a new Cβ measure and updated Ramachandran plot, and Favored and allowed ϕ,ψ regions are also defined for Pro, pre‐Pro, and Gly (important because Gly ϕ‐ψ angles are more permissive but less accurately determined).
